Sets the default boot flags and, for OpenVMS, a root number.
Boot flags contain information used by the operating system to determine some aspects of a system bootstrap. Under normal circumstances, you can use the default boot flag settings.
To change the boot flags for the current boot only, use the flags_value argument with the boot command.
set boot_osflags flags_value
The flags_value argument is specific to the operating system.
Tru64 UNIX systems take a single ASCII character as the flags_value argument.
|
Flag |
Effect |
|
a |
Load operating system software from the specified boot device (autoboot). Boot to multiuser mode. |
|
i |
Prompt for the name of a file to load and other options (boot interactively). Boot to single-user mode. |
|
s |
Stop in single-user mode. Boots /vmunix to single-user mode and stops at the # (root) prompt. |
|
D |
Full dump; implies "s" as well. By default, if Tru64 UNIX crashes, it completes a partial memory dump. Specifying "D" forces a full dump at system crash. |
OpenVMS systems require an ordered pair as the flags_value argument: root_number and boot_flags.
|
root_number |
Directory number of the system disk on which OpenVMS files are located. For example:
| ||||||||||
|
boot_flags |
The hexadecimal value of the bit number or numbers set. To specify multiple boot flags, add the flag values (logical OR). For example, the flag value 10080 executes both the 80 and 10000 flag settings. See the boot flag settings table. |
